United States Patent BASEBOARD HEATER Peter Krassowski, Boyertown, Pa.

Application March 24, 1954, Serial No. 418,274

1 Claim. (Cl. 257-433 This invention relates to a heater and moreparticularly to a baseboard heater, and it consists in theconstructions, arrangements and combinations herein described andclaimed.

It is the cardinal object of the invention to provide a heater of theconvection type which may be readily installed in the baseboard of roomsof a dwelling or other enclosures.

More specifically, it is an important object of the invention to providea heater which embodies a plurality of disks suitably coupled together,each disk having a bore, which when in assembled relation forms apassage for the heating medium; each disk having a plurality of spaced,tapered radiating fins for even distribution of heat within a room orother enclosure.

It is also an object of the invention to provide a heater of thecharacter described in which a front cover or heat deflecting shield ismounted upon the baseboard of a room so as to conceal the heater andwhich is detachable, enabling ready cleaning of the heater and the floorsurfaces of dust or other foreign matter.

Additional objects, advantages and features of invention will beapparent from the following description, considered in conjunction withthe accompanying drawings, wherein,

, Figure l is a perspective view of the heater with the heat deflectingshield in position, part of which is broken away.

Figure 2 is a front elevation with the shield removed.

Figure 3 is a fragmentary longitudinal sectional view through theheater.

Figure 4 is a vertical section through the heater.

Figure 5 is a plan view of one of the heating disks.

Figure 6 is a cross section of the line 6-6 of Figure 5.

Figure 7 is an end elevation of one of the end members, and

Figure 8 is a fragmentary detail showing the heat deflecting shield ashinged to the wall.

There is illustrated a heater generally indicated by the referencecharacter 10 having a heat medium inlet 11 and an outlet 12.

The heater 10 is supported above the floor of an enclosure, such as aroom, by a suitable number of lag screws 13 spaced between a pair ofdisks 14 and secured in studding 15 of the wall of the enclosure. Afront cover or hot air deflecting shield 16 is employed to conceal theheater 10 and for this purpose includes an upper arcuate portion 17having a downwardly turned flange 18 suitably notched as at 19 to engageover a headed screw 20 secured in the plaster 21, plaster board 22 andthe studding 15. The shield has a downwardly extended skirt 23 of alength extending slightly below the lag bolts 13 so as to engage theheads thereof for lateral support. The respective ends of the skirt 23may be formed as ornamental legs 23'. If desired, the shield 16 may behingedly connected to a wall surface as indicated at 24 and shown inFigure 8. Any suitable grill 25 may be formed in the shield for theoutflow of hot air.

2,775,431" Patented Dec. 25, 1956 m ICC The heater comprises a series ofdisks 14 secured between respective end members 26 and 27 as will now bedescribed, reference being hadto Figure 4. i

The end members 26 and 27 are of identical construction and are of heavycast iron formed with four openings 28, circumferentially spaced withrespect to an axial threaded opening 29 for receiving threaded ends ofthe inlet and outlet 11 and 12. The end members 26 and 27 are formedwith a pair of flat faces 30. If desired, an intermediate plate 31 maybe employed which has a contour corresponding to the end members 26 and27 and has a bore 32.

As shown in Figures 5 and 6, the heating disks 14 embody a cast ironbody 33 of substantial thickness having an axial opening 34 which, asshown in Figure 6, is of tapered formation, the lesser diameter beingpresented to the next adjacent disk in the direction of the outflow ofthe heating medium. The disks 14 include a plurality of tapered, radialfins 35 formed integrally with the body 33, two opposed fins 35' beingof shorter length so that the heater unit when assembled will align withthe flat faces 30 of the end members 26 and 27, this constructionpermitting close spacing of the unit with a reflector 36 positionedbehind the heating unit. As shown in Figure 3, where a lag bolt 13 ispositioned so as to intersect a fin 35, such fin may be shorter than theother fins so as to rest upon the lag bolt. However, the lag bolt may beaccommodated between a pair of fins if desired.

Four tie rods 37 are employed for securing the heating unit disks 14 inassembled relation, these bolts being extended through the openings 28of the end members 26 and 27 and between paired fins 35. One end of thetie rods 37 is formed with left hand screw threads, while the other endis provided with right hand screw threads for receiving correspondinglyformed nuts 38. This formation of threads ithas been found, overcomes atwisting torque under heating and prevents looseness between gaskets 39interposed between respective disks.

In use, the heating medium enters the unit 10 through the inlet 11 andpasses through the series of disks 14 to the outlet 12. The disks willbecome quickly heated, the fins 35 and 35 radiating heat in radialdirections, thus providing a uniform heat and by virtue of terminationof the skirt 23 above the floor level, an eflicient upward and outwardcirculation of air is provided.

It will be understood that the heating unit 10 may be assembled indifferent lengths, the only requirement being that tie rods 37 are ofproper lengths.

While I have shown and described a preferred form of the heating unit,this is by way of illustration only, and I consider as my own, all suchmodifications in construction as fairly fall within the scope of theappended claim.

I claim:

A baseboard heater comprising a series of horizontally spaced cast irondisks, each disk having a body member arranged in abutting relation witha gasket and the body of the next adjacent disk to provide a heater ofelongated form, each of said body members having a tapered heat mediumpassage therethrough, each of said disksfurther having a plurality ofradially disposed spaced apart tapered fins, an end member abuttingrespective end disks and having a gasket therebetween, said end membersbeing apertured for reception of tie rods extended between certain pairsof fins of said disks, said tie rods including nuts for securing thedisks in assembled relation, one end of said tie rods being formed withleft hand screw threads, while the other end of said tie rods are formedwith right hand screw threads, and each end member having a threadedaxial opening for connection of standard pipe of a heating system.
